Production of PogoPin Connector

　　1. Pogo pin is a spring-type probe formed by riveting and pre-pressing the three basic parts of needle, spring and needle tube through precision instruments. Because of its precise structure and small size, pogo pins can reduce the weight of products, save space and beautify the appearance of products. They are widely used in electronic products in the fields of communication, automobile, medical, aerospace and other fields.

　　2. At present, the common pogo pin needles on the market are designed with a bevel structure, a punching structure and a flat bottom structure; among them, the reverse drilling design of the pogo pin needle punching structure, the length of the supporting spring can exceed the length of the needle tube. In the case of limited space, the excellent performance of stable elasticity and stroke can be obtained, occupying a place in its field.

　　3. However, the pogo pin with the existing anti-drilling design may be instantaneously disconnected in a vibration environment, resulting in excessive jumping of its resistance value.

　　4. The above content is only used to assist the understanding of the technical solution of the utility model, and does not mean that the above content is the prior art.

　　5. The main purpose of this utility model is to propose a pogo pin connector, which aims to solve the problem of large resistance jump of the pogo pin connector.

　　6. In order to achieve the above purpose, the pogo pin connector proposed by the present utility model, the pogo pin connector includes:

　　7. A needle tube, wherein an accommodation cavity with an opening is formed in the needle tube;

　　8. A needle, one end of the needle is installed in the accommodating cavity, and the needle is provided with a first installation groove on the bottom wall facing the accommodating cavity;

　　9. Preferably, the angle range of the second cone angle is 0

　　10. A needle cap, slidably installed in the first installation groove along the depth direction of the first installation groove, the outer side wall of the needle cap is in contact with the first installation groove, the needle cap A second installation groove is provided on the bottom wall facing the accommodating cavity, and the bottom end of the outer side wall of the needle cap protrudes outward to form a brim;

　　11. A snap ring, the snap ring is provided with a fracture, the snap ring is sleeved on the outer side wall of the needle cap, and is located between the cap brim and the bottom end of the needle; and

　　12. An elastic piece, one end of the elastic piece protrudes into the second installation groove, and the elastic piece is located between the bottom wall of the needle tube and the top wall of the needle cap.

　　13. Preferably, the top surface of the needle cap is tapered to form a first taper angle; the top wall of the first installation groove is tapered to form a second taper angle; the first taper angle is smaller than the second cone angle.

　　14. Preferably, the angle range of the first cone angle is 0
